Nassau Financial Group offers specific Medigap plans, such as Plan F, Plan G, and Plan N, which help pay for Medicare-approved costs left over by Original Medicare.
To purchase a Nassau Medigap plan outside of your open enrollment period, you may be subject to medical underwriting and could be denied coverage based on pre-existing conditions.
Like all Medicare Supplement insurance, Nassau plans are guaranteed renewable, meaning the policy cannot be canceled as long as you pay the premiums.
Longevity in the insurance industry isn't just a talking point — it's a signal of financial resilience. Nassau Financial Group has been operating since 1851, making it one of the older names in the American insurance landscape. Headquartered in Hartford, Connecticut, the privately owned company has spent more than 170 years helping individuals and families protect their financial futures through a range of insurance and financial services products. That legacy of stability is especially relevant for Medicare Supplement policyholders, who depend on their insurer to reliably cover costs year after year.
Nassau Financial Group offers Medicare Supplement insurance — commonly called Medigap — to help fill the coverage gaps that Original Medicare leaves behind. Their lineup includes Plan A, Plan F, Plan G, and Plan N. Each plan is designed around a different balance of coverage breadth and monthly cost — so the best choice depends on your health situation, your risk tolerance, and how much predictability you want in your healthcare spending.
Nassau Financial Group's Medicare Supplement plans are available in a select group of states, including Connecticut, Georgia, Illinois, Indiana, Kansas, Kentucky, Michigan, Missouri, Nebraska, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, and Wisconsin. Availability can vary, so if your state isn't on this list, it's worth confirming directly with Nassau or a licensed insurance agent before assuming coverage isn't accessible to you.
Nassau Financial Group holds an A- rating from A.M. Best — a designation that signifies an excellent ability to meet financial obligations. For a Medigap policyholder, that's an important benchmark: it tells you the company is well-positioned to pay claims reliably.
The company has not been independently rated by S&P, Moody's, Fitch, or JD Power, which means less third-party data is available than with some larger carriers. That doesn't disqualify Nassau from consideration, but it is worth factoring into your comparison process.
Nassau Financial Group offers a household discount of up to 12% when two or more people from the same household enroll in their Medicare Supplement plans — one of the more generous household discount tiers available among Medigap insurers.
To qualify, both individuals must live at the same address and be enrolled in a Nassau Medigap plan. The exact discount percentage can vary by location and the specific plan chosen, so it's worth confirming the exact savings available in your state.
